Recommended by The American Thoracic Society, nose clips have been proven to significantly improve PFT test results. The less air that escapes from the nose, the more accurate the result. That’s what sets The Klip™ apart from typical nose clips. With no bulky pads, it offers the snuggest, most comfortable fit available.
